Agronomic and Economic Performance of Rain-Fed Maize (Zea mays L.) Production under Varying Sowing Dates and Multinutrient Fertilizer Levels in Shire Area, Northern Ethiopia

Figure 2

Effect of sowing dates as main plot and multinutrient fertilizer application levels in the subplot on ear length (a), number of rows per ear (b), and number of kernels per row (c) in two consecutive growing seasons in 2018-2019 and their average values. Vertical bars represent the standard error of the mean. The treatments are noted as SD1, sowing date 1 (June 1 in 2018 and May 26 in 2019); SD2, sowing date 2 (June 7 in 2018 and June 3 in 2019); SD3, sowing date 3 (June 12 in 2018 and June 8 in 2019); SD4, sowing date 4 (June 16 in 2018 and June 12 in 2019): F0, no fertilizer application; F1, 100 kg·ha⁻¹; F2, 200 kg·ha⁻¹; F3, 300 kg·ha⁻¹ multinutrient fertilizer levels.
